[Featrue](default value) add pi as default value (#36280)
## Proposed changes
Issue Number: refers https://github.com/apache/doris/issues/34228
<!--Describe your changes.-->
add pi as default value, such as:
```sql
CREATE TABLE IF NOT EXISTS t1
(
k TINYINT,
v double not null DEFAULT PI
)
UNIQUE KEY(k)
DISTRIBUTED BY HASH(k)
PROPERTIES("replication_num" = "1");
```
